Daniel Magana, 35, of the 6600 block of Monroe Avenue in Hammond, is charged with two counts of misdemeanor DUI and one count of misdemeanor reckless driving. He was also cited with failure to yield to emergency vehicles, police said.

The police SUV was parked in the 1300 block of North Clark Street when it was hit head-on around 3:30 a.m. Sunday, Police News Affairs Officer Hector Alfaro said. The officers had been completing paperwork from another traffic crash, police said.

A person in the back of the squad car and a police officer were taken to Northwestern Memorial Hospital, where they were stabilized, Alfaro said. The other officer was taken to Advocate Illinois Masonic Medical Center, Alfaro said, where his condition was also stabilized.

Magana told police he had been drinking and had fallen asleep at the wheel, according to a police report.

Officers smelled a strong odor of alcohol and Magana was placed into custody. While at the Near North District police station, he had trouble keeping his balance and, after performing a breath test, he told police he'd had 14 cups of beer while at the Cubs game Saturday at Wrigley Field and after the game at the home of a friend, the report said.

His blood alcohol content was measured at 0.193, more than twice the legal limit of 0.08, the report said.
